Audio/IEMs
“Excellent value Chi-Fi IEM under $50. The KZ Castor delivers detailed, balanced sound with tuning flexibility that punches well above its price tier—particularly the Harman version that competes with options costing 4x more. At current prices (~$20-35), it's a strong buy for budget-conscious audiophiles.”
